Lead gen
Website lead capture
A landing-page form posts to a dynamic endpoint, and the lead is scored, assigned, and answered before a rep ever opens it.

Integrations & developer access
Open to everything. Tied to no one.
Flexie is built to connect, not to fence you in. Your email, calls, and messaging run on your own provider accounts. Data flows in through secure endpoints and out through webhooks. A full REST API and an MCP server for outside AI agents put every record within reach, all under permissions you set.

Channels
Email, calls, and messaging on accounts you already own.
Flexie does not resell you a phone line or a mailbox. You connect the provider accounts you already pay for, your Gmail or IMAP, your Twilio, your WhatsApp Business number, your Stripe, and Flexie runs the conversations and payments through them. The data lands on the right record; the relationship with the vendor stays yours.
Email, two ways
Google, Microsoft, or any IMAP and SMTP mailbox, synced both ways, not just outbound.
SMS and WhatsApp
Send and receive on your own Twilio or WhatsApp Business number, attached to the customer.
Calls on your line
Telephony through Twilio or your own self-hosted PBX, with logs and recordings on the record.
Calendars in sync
Two-way with Google and Microsoft, so availability and meetings stay current.
Payments you own
Connect your Stripe or PayPal for invoice and subscription payments, reconciled in Flexie.
Your vendor, your bill
Every channel runs on your account, so you are never locked to a number Flexie controls.
Data in
A secure door for data to come in. Just a URL and a workflow.
When a website, an app, or a partner system needs to push data into Flexie, you give it a private endpoint. The moment something arrives, Flexie turns the request into a record and runs a workflow on it, looking things up, creating or updating records, replying to the caller. Often that is the whole integration, with nothing to build on the Flexie side.
A URL, not a project
Stand up a secure endpoint inside a workflow, in the visual builder. No servers to run, nothing to deploy.
Turns requests into action
Each incoming request becomes a record a workflow can read, decide on, and act on.
Capture leads from anywhere
Your website or landing page posts a form and a qualified lead lands in seconds.
Receive any webhook
A payment, an order, or a status change from another tool fires a flow the instant it arrives.
Reply in the same call
Return a response to the caller, so an endpoint can back a small custom API.
Secured and controlled
Authentication and cross-origin rules are handled for you, and you can switch it off anytime.
Data out
The moment something happens, your other tools know.
When a deal is won, an invoice is paid, or a record changes, Flexie can tell the rest of your software straight away. Webhooks push the event out with signed payloads, automatic retries, and a delivery log, so nothing has to be copied from one screen to another by hand.
Fires on any event
A new customer, a paid invoice, a won deal, any record change can trigger an outbound push.
Keeps your tools in step
Your accounting, data warehouse, or team chat hears about it the second it happens.
Delivered, not dropped
Failed deliveries retry on their own, and every attempt is logged for you to see.
Plug into Zapier, Make, n8n
Reach thousands of apps through the automation tool your team already uses.
Signed and verifiable
Payloads are signed, so the receiving system can trust the message really came from Flexie.
Built from a workflow
The same visual builder that runs your business decides what goes out and when.
Build on it
Read and write every record. Build the connection you need.
When an off-the-shelf connector will not do, your developers get a full REST API over every record in Flexie, on standard authentication, with pagination and filtering. For logic too specific for any screen, they write Flexie Scripting and stand up their own endpoints, all without leaving the platform the rest of the team runs on.
Every record, both ways
Read and write leads, deals, invoices, cases, and your own custom records over one API.
Standard, predictable auth
Token authentication, pagination, and filtering work the way your developers expect.
Your own endpoints
Build custom HTTP endpoints inside Flexie, with auth and cross-origin already handled.
Logic no dropdown holds
When a rule is too specific to configure, write it directly in Flexie Scripting.
Live answers, no extra storage
Expose computed data as virtual records your systems can query like a table.
Connect on your terms
Run integrations on your own credentials and endpoints, never boxed into a vendor's list.
AI Agents · MCP
Hook your AI agents into Flexie's MCP server.
Flexie provides an MCP server, an implementation of the Model Context Protocol, the open standard for connecting AI to business software. Hook your AI agent into it and, just by asking, it can look up customers, pull reports, and trigger automations in Flexie, always inside the permissions of the person who connected it. This is on top of Flexie's own built-in AI workforce.
A real MCP server
Any MCP-compatible agent connects to it directly, so wiring one up is configuration, not a development project.
Works on your real data
An agent can look up customers, read reports, and start automations against your live workspace.
Inside your permissions
It only ever sees and does what the person who connected it is allowed to.
Approvals still apply
Anything material still asks for a yes before it happens, the same as everywhere in Flexie.
On top of Flexie AI
Separate from, and in addition to, Flexie's own AI workforce that runs inside the platform.

Before you integrate
The best integration is the one you never have to build.
Most integrations exist to copy data between tools that do not talk to each other: the CRM, the billing tool, the help desk, the spreadsheet. In Flexie those are not separate tools. Sales, billing, communication, and support run on one engine, sharing one copy of every customer, deal, and invoice.
So before reaching for a connector, it is worth checking what already happens inside Flexie on its own. A won deal that raises an invoice, a paid invoice that closes a case, a message that lands on the right record, none of that needs an integration, because it never leaves the platform. The connections that remain are the few that genuinely reach outside, and those are what the rest of this page is for.
What teams connect
Real connections, not a logo wall.
Six things businesses wire up with Flexie’s open model, every one built on the endpoints, webhooks, API, and channels above, not a marketplace of pre-canned apps.
Finance
Payment reconciliation
A Stripe webhook lands the moment a payment clears. Flexie marks the matching invoice paid and updates the balance to the cent.

Back office
Accounting kept in sync
Won deals and paid invoices push out to your accounting tool, so the books match Flexie without anyone re-keying numbers.

Open, under control
Opening Flexie up never means giving up control.
Every connection, whether it is another tool, a developer’s app, or an AI agent, gets only the access you grant it. Every request is checked against your permission rules. Anything material still asks for approval before it happens. And you can see what is connected and switch any of it off, the moment you want to.
Granted, not assumed
A connection only ever gets the access you give it, nothing more.
Checked every request
Each call is measured against your permission rules before it runs.
Approval on what matters
Material actions still pause for a yes, the same as everywhere in Flexie.

Plain speak
An open platform, not a connector marketplace. Know which you want.
Flexie connects to almost anything through endpoints, webhooks, and an API, on your own terms. That is power for teams who want to own their integrations, and the wrong shape for teams who just want to pick an app from a list.
Where Flexie’s open model fits
- You want your email, calls, and messaging to run on the provider accounts you already own.
- You have a website, app, or partner system that needs to push data into your CRM.
- You want other tools updated the instant something happens, not on a nightly export.
- You have developers who would rather build on a real API than wait on a vendor's roadmap.
- You want outside AI agents to reach your data safely, under your permissions.
- You would rather own and control your connections than rent them from a marketplace.
Where it is not the right tool
- You want to browse a marketplace and switch on a pre-built app in two clicks.
- You have no one technical and need every integration fully managed for you.
- You only need a one-time CSV import, not a living connection between systems.
- Your other tools have no webhooks or API of their own to connect to.
- You want a single bundled price with every connector included and no setup.
- Your needs are simple and a stock tool's native integrations already cover them.
